STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not Applicable.

BACKGROUND

Traditionally, producing plans for highway (and other roadway) design involves a number of individual computing programs. Often, the inputs and/or outputs of one program must be converted to a different format in order to be compatible with other programs. For instance, in one aspect, roadway design involves extracting boring samples from a plurality of locations within a geographical boundary of interest (e.g., a highway design corridor) to determine sub-surface geologic composition. The boring samples may then be utilized to create boring logs which may subsequently be plotted in a number of different ways to produce graphical representations of the geotechnical data within the geographical boundary. One way in which such graphical representations may be produced is by utilizing a series of programs in the PLBORING family of programs. Converting the graphical representations (e.g., produced utilizing one or more of the PLBORING programs) to a format that complies with a multitude of varying standards, whether government regulated or imposed by preference, is an additional step that may involve, for instance, a VAX-based family of programs.

To further illustrate the point, a DOS-based program, e.g., gINT, may be utilized during the above process to produce an electronic version of the boring logs. However, in this instance, the gINT input must be converted to a format compatible with the VAX in order to make use of the PLBORING family of programs.

In view of the above, it can be readily appreciated that producing highway design plans utilizing all of these initially non-compatible programs, and making them compatible with one another, is a time-consuming and manually intensive process. Further, personnel that are trained and efficient in using all of the individual programs are limited, further exacerbating the timing issue.

Although the various blocks of FIG. 1 are shown with lines for the sake of clarity, in reality, delineating various components is not so clear, and metaphorically, the lines would more accurately be gray and fuzzy. For example, one may consider a presentation component such as a display device to be an I/O component. Also, processors have memory. We recognize that such is the nature of the art, and reiterate that the diagram of FIG. 1 is merely illustrative of an exemplary computing device that can be used in connection with one or more embodiments of the present invention.

Turning now to FIG. 2, a block diagram is shown illustrating an exemplary integrated computing system 200 for applying information associated with at least one sub-surface stratum within a geographical boundary of interest to an engineering plan for designing a surface (e.g., a highway or other roadway), in accordance with an embodiment of the present invention. System 200 includes a user computing device 210, a server 226 and a database 228, the database being configured as a data repository. (It will be understood that database 228 may be integrated within the user computing device 210 rather than provided as an external component, if desired.) Each of the user computing device 210 and the server 226 may be any type of computing device, such as computing device 100 described with reference to FIG. 1, for example.

The user computer 210, the server 226, and the database 228 are in communication with one another via a network 224, which may include, without limitation, one or more local area networks (LANs) and/or wide area networks (WANs). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet. It will be understood and appreciated by those of ordinary skill in the art that any number of user computing devices, servers, databases, and networks may be employed within system 200 within the scope of embodiments of the present invention and that the illustrated embodiment is merely exemplary. In fact, all necessary information may be input directly into the user computing device 210 without the need for a network 224, server 226, or external database 228 at all. Additionally, other components not shown may also be included within the system 200 in accordance with embodiments hereof.

User computing device 210 includes a boring log receipt module 212, a ground surface model receipt module 214, an engineering plan receipt module 216, a digital terrain model (DTM) generating module 218, a DTM updating module 220, and a data preparation module 222. It will be understood and appreciated by those of ordinary skill in the art that the modules illustrated in the user computing device 210 of FIG. 2 are shown by way of example only and that user computing devices having fewer than all of the illustrated modules, as well as user computing devices having additional modules that are not shown, are contemplated to be within the scope of embodiments of the present invention.

Boring log receipt module 212 is configured to receive boring log data from a plurality of borings, each of the borings representing a location within a geographical boundary of interest. For instance, in designing a roadway, a geographical boundary resembling a corridor having outer limits which exceed the dimensions of the roadway by a predetermined distance may comprise the geographical boundary of interest. To gain an understanding of the sub-surface material location and composition within the geographical boundary of interest, a plurality of boring samples may be collected from various point locations within the boundary. Each of the point locations may be defined by at least two coordinates (e.g., an X coordinate and a Y coordinate) or defined relative to a baseline, for instance, by station and offset. The samples may then be utilized to generate boring logs, i.e., reports, that include text and/or graphics specifying material type classifications and locations. In embodiments, the boring log receipt module 212 may be configured to receive the boring logs. Additionally, the boring log receipt module 212 may be configured to re-define the point location of one or more borings as a coordinate location where such point locations are provided relative to a baseline.

If desired, the boring logs may be plotted such that they may be presented according to particular requirements. For instance, the boring logs may be plotted such that they may be graphically displayed on a display device (not shown) associated with the user computing device 210 in plan, profile, and/or section. In embodiments, the boring logs may be plotted and graphically displayed in association with a profile and/or a section view, as more fully described below with reference to FIG. 5. Plotting of the boring log data is useful in surface design as it permits extrapolation of data between the point locations of the borings. Though not illustrated in FIG. 2, system 210 may include a boring log plotting module configured to plot the received boring logs. Alternatively, the boring log receipt module 212 may be configured not only to receive the boring log data but also to plot the received data as desired. Any and all such variations, and any combination thereof, are contemplated to be within the scope of embodiments of the present invention.

The ground surface model receipt module 214 is configured to receive ground surface information associated with the geographical boundary of interest. Ground surface information may be represented, for example, as one or more DTMs providing a three-dimensional representation of the ground line as it exists in the geographical boundary of interest prior to implementation of the surface being designed. Providing the system with the dimensions and contour of the ground line over which a surface is to be designed permits greater accuracy in the roadway design and allows changes in horizontal alignments to be made without having to gather and input new data, as more fully described below.

At times, the ground surface information may indicate one or more material outcrops comprised of a material included in a sub-surface stratum of interest. In such circumstances, systems according to embodiments of the present invention are configured to take into account these material outcrops and recognize and adequately account for intersection of a material outcrop with the ground line, as more fully described below.

The engineering plan receipt module 216 is configured to receive the design data associated with the desired surface. Accordingly, the engineering plan receipt module 216 is configured to receive data representing the horizontal alignment of the surface being designed. The horizontal alignment data provides a reference point for the borings such that the sub-surface material composition that may affect the surface design may be more readily understood. Horizontal alignment data received by the engineering plan receipt module 216 may be user-created data, data imported into the system 200, or any combination thereof. Additionally, horizontal alignment data representing a plurality of horizontal alignments may be received, if desired, and utilized in generating a digital terrain model, as more fully described below.

Horizontal alignment data often times includes at least one endpoint defined by the boring log data. That is, horizontal alignments are often generated such that they begin and end with the actual point location of a boring sample and define a corridor there between. In some instances, it may be desirable to extend the corridor transverse to the horizontal alignment. In this regard, the illustrated system 200 is configured to extend the corridor transverse to the horizontal alignment without receipt of additional boring log data (e.g., false or “dummy” boring log data or the like). Accordingly, the engineering plan receipt module 216 may be configured to perform such corridor “widening” or a separate module (not shown) housed on either the user computing device 210 or a server 226 accessible through the network 224 may be provided. Any and all such variations, and any combination thereof, are contemplated to be within the scope of embodiments of the present invention.

The DTM generating module 218 is configured to generate a digital terrain model (DTM) that represents the material composition of at least one sub-surface stratum (that is, at least one sub-surface layer) with the geographical boundary of interest. The DTM generating module 218 takes into account the boring log data received through the boring log receipt module 212, the ground surface information received through the ground surface model receipt module 214, and the horizontal alignment data received through the engineering plan receipt module 216 in generating the representative DTM.

The DTM updating module 220 is configured to update any DTM generated by the DTM generating module if boring log data, ground surface information, or horizontal alignment data that was utilized in generating the DTM is modified. For instance, during the surface design process, the parameters of the geographical boundary of interest may be modified if the boring log data indicates a material composition that may cause a problem if the design proceeds as originally desired. Upon modifying the horizontal alignment, and receipt of the modification by the engineering plan receipt module 216, the DTM updating module 220 is configured to generate an updated DTM taking into account the modified horizontal alignment data. For instance, as the horizontal alignment data provides a reference point for the borings, upon receipt of updated horizontal alignment data, the boring log data associated with the DTM may be transferred and utilized to generate an updated DTM. It will be understood and appreciated by those of ordinary skill in the art that the DTM generating module 218 and DTM updating module 220 may not be two separate modules as illustrated but may be presented as a single module capable of generating original and updated DTMs. Any and all such variations are contemplated to be within the scope of embodiments of the present invention.

In addition to generating DTMs representing the material composition of at least one sub-surface stratum within a geographical boundary of interest, the illustrated system 200 is capable of preparing data for use in, e.g., determining the volume of a given material present in the sub-surface stratum and/or preparing data for generating surface contour maps and the like. As such, the user computing device 210 additionally includes a data preparation module 222. The data preparation module 222 is configured to utilize the boring log data received by the boring log receipt module 212, as well as any necessary extrapolations between boring log point locations, to prepare data for a variety of purposes including, but not limited to, determining the volume of a given material in the at least one sub-surface stratum, preparing data for generating surface contour maps and/or other graphical and or quantity-determining purposes.

Additionally, as previously discussed, occasionally the ground surface information may indicate the presence of at least one material outcrop that is comprised of a material included in at least one sub-surface stratum. In such circumstances, the data preparation module 222 may be additionally configured to take into account the volume of material in the outcrop (which may be input or imported from a volume determining external application or module), as well as the sub-surface material volume (which, again, may be input or imported from an appropriate external application or module), in preparing the data to determine the overall material composition.

With reference to FIG. 3, a flow diagram is illustrated showing an exemplary method 300, in an integrated computing environment, for generating a digital terrain model (DTM) representing at least one sub-surface stratum within a geographical boundary of interest (e.g., a highway design corridor), in accordance with an embodiment of the present invention. Initially, as shown at block 310, boring log data is received (e.g., by boring log receipt module 212 of FIG. 2). The boring log data relates to a plurality of borings, each of the plurality of borings representing a location within the geographical boundary and including information associated with the at least one sub-surface stratum. As previously mentioned, such boring log data may be received directly or received in a plotted format for presentation, as desired.

Next, ground surface information associated with the geographical boundary of interest is received (e.g., by ground surface model receipt module 214 of FIG. 2), as shown at block 312. In one embodiment, the ground surface information may be provided by virtue of one or more DTMs. Subsequently, as indicated at block 314, horizontal alignment data representing one or more horizontal alignments is received (e.g., by engineering plan receipt module 216 of FIG. 2). The horizontal alignment data may include user-created data or data imported from one or more external applications or modules. It will be understood and appreciated by those of ordinary skill in the art that the method steps shown in blocks 310, 312 and 314 may be completed in any successive order, simultaneously, or any combination thereof within the scope of embodiments of the present invention.

Subsequently, as indicated at block 316, a digital terrain model is generated representing the at least one sub-surface stratum within the geographical boundary of interest. The DTM may be generated, for instance, by DTM generating module 218 of FIG. 2, taking into account the boring log data, ground surface information and horizontal alignment data.

Referring now to FIG. 4, a flow diagram is illustrated showing an exemplary method 400, in an integrated computing environment, for generating a geologic profile representing at least one sub-surface stratum within a geographical boundary of interest, in accordance with an embodiment of the present invention. Initially, as indicated at block 410, boring log data is received (e.g., by boring log receipt module 212 of FIG. 2). The boring log data relates to a plurality of borings, each of the plurality of borings representing a location within the geographical boundary and including information associated with the at least one sub-surface stratum. As previously mentioned, such boring log data may be received directly or received in a plotted format for presentation, as desired.

Next, as indicated at block 412, one or more ground surface DTMs is received, the ground surface DTM being associated with the geographical boundary of interest. The ground surface DTM(s) may be received, for instance, by ground surface model receipt module 214 of FIG. 2. Subsequently, a geologic profile representing the material composition of the at least one sub-surface stratum may be generated, e.g., by data preparation module 222 of FIG. 2. This is indicated at block 414.

Turning now to FIG. 5, an illustrative screen display of an exemplary user interface configured to simultaneously display at least one geologic profile and boring log indicators is shown and designated generally as reference numeral 500. It will be understood by one of ordinary skill in the art that screen display 500 is shown by way of example only and is not intended to limit the scope of embodiments of the present invention in any way.

Screen display 500 includes a side view display area 510 and a top view display area 512. Each of the side view display area 510 and the top view display area 512 include boring log indicators 514 and a geologic profile 516 thereon. Simultaneous display of both boring log indicators 514 and a geologic profile 516 permits the user to view surface contours and material composition at the same time and to effectively connect points to one another in designing a desired surface.

It will be understood by those of ordinary skill in the art that each of the side view display area 510 and the top view display area 512 may be displayed independent of one another within the scope of embodiments of the present invention Likewise, additional views of the geologic profile which illustrate both boring log indicators and surface contours, though not shown, are within the scope of embodiments hereof.

As can be understood, embodiments of the present invention provide integrated computing systems and methods for applying sub-surface material location and composition information to engineering plans for designing surfaces, e.g., highways and other roadways. Utilizing the described systems and methods, surfaces may be more efficiently designed in a timely fashion, requiring less format conversion for inputs and outputs to be compatible throughout the design process. Additionally, adjustments for changes in alignments for the desired surfaces are more easily taken into account than in conventional design systems, permitting quicker design corrections and more accurate results.

The present invention has been described in relation to particular embodiments, which are intended in all respects to be illustrative rather than restrictive. Alternative embodiments will become apparent to those of ordinary skill in the art to which the present invention pertains without departing from its scope.
